led certain new and useful Improvements in PaperBottles and Processes of Manufacturing Same, of which the following isa speciication.

rIhis invention relates Vto improvementsv in paper bottles and the process of manufacturing the same, particularlyto multiple ply ypaper bottles which are especially adapted for use as milk bottles, although of course they may be used for a variety of purposes.

The objects of the invention are, First, to provide an improved construction of-Inultiple ply paper bottle which can be very readily manufactured.

Second, to provide an improved breast and neck construction for such bottle.

rIhird, to provide an improved bottom con v struction for suchbottle..

Further objects and objects relating to details and economies of construction and op,

'eration will definitely appear from the detailed description to follow.

I accomplish the objects of my invention bythe devices and means described in the following specifi-cation. rllhe invention is clearly defined and pointed out in the claims.

Structures illustrating preferred embodiments of my invention are shown in the aclcompanying drawings, forming a part of' this specication, in which:

Figure I is an elevation view of a bottle embodying the features of my invention. j

Fig. II is an enlarged detail transverse sectional view taken on a line corresponding to line 2 2 of Fig. I. i

Fig. III is an enlarged detail sectional view taken on a line corresponding to line 3 3 of Figs. I and V, showing the details of the arrangement of the folds 1n the paper.

Fig. IV is an enlarged detail sectional view taken on a line corresponding to line 4 4 of Fig. I, showing details of construction of the bottom portion.

Fig. V is an enlarged detail sectional view taken on a line corresponding to line 5 5 of Figs. I and III.

Fig. VI is an enlarged detail sectional view, taken on a line corresponding to line 3 3 of Figs. I- and V, of a modified form of the wall structure of the neck.

Fig. VII is a detail sectional view similar to that of Fig. IV, showing a modiiication of the bottom in that it is not embraced in the bottom crease.

Figs. VIII, IX, X, XI and XII are details of modifications of the formation of the neck part, particularly in regard to reinforcingthe same and to the formation of the groove in the cap.

In thedrawings, similar numerals of reference refer to similar parts throughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing the body of the bottle 1 is cylindricall in form, maderup of plies 2 of paper which are creased and conformed into the breast of the bottle at 3 and rolled into a cylindrical neck 4 in which is formed an angular crease 5, the same being formed length- Lwise of the bers of the paper. The neck is expanded at 6 'and the cap 7 is inserted in the crease, as seen in Fig. V.

Each layer of paper 1s creased in forming the neck, as seen at 4', and the creased portions overlapping each other break joints and make a very secure breast and neck to the bottle, the whole being rolled from a sheet and conformed by' hot rollers with suitable cement to shape the same, and the whole being thereafter suitably parati'lned.

'Ihe groove 5 has an angular portion at 8 with a downwardly sloping portion to receive the cap, like the structure described n my concurrent patent application filed J anuary 19, 1916, Serial No. 73,003.

The bottom of the walls of the cylindrical portion of the bottle is folded back on itself with portions at 10 within which is inserted the bottom 11 with a downwardly projecting ange 12, the-whole being crimped by suitable die rolls at 9 to retain the arts securely in place and to increase the rigidity of the lfnplttm. rIhe whole structure is then paraf- In Fig. VII I show a modification of this bottom, similar to Fig. IV, in which the bottom is not flanged and extended between therequiring an extra operation. I wish to claim specically the preferred form and also a claim sufficiently broad to embrace both structures.

.In Fig. VIII a modification is shown in which the bottle is formed of a single ply. In Fig.l IX the bottle is shown formed of double plies, the upper portion being folded back as a reinforce and finish, the edge forming a portion of the retaining groove, it not being necessary in this form to make the sharp angle in the wall of the paper.

In Fig. X I show a structure like that appearing in Fig. IX with the angle in the groove. lIn Fig. XI I show the finish at the top of the bottle formed by folding the ply of the wall outward, the wall being of single ply. In Fig. XII I show a single ply wall with the top folded inward and extended down as a reinforce and finish, the edge assisting in forming the groove for the cap.

I have thus described the structure in its preferred form. It will be seen that it is possible to Wrap this paper directly onto a- ,I

mandrel or form, crease the same as'y it is paid out, forming the bottle of one or more plies, and then paraffin the same. Thebottom should be preferably retained as I have indicated in Fig. IV, but may be otherwise inserted. The variations that I have described show that the structure can be considerably modified without departing from my invention. I desire, however, to claim the same specifically as well asbroadly as pointed out in the appended claims.

Having thus described my invention what I claim is new and desire to secure by Letters Patent is:

1. The process of forming a bottle consisting in forming a cylindrical body of a plurality of plies of paper, separately creasing the plies at one end of said body to form plaits and rolling said plaits in overlapping relation to form the breast and neck of said bottle, and pressing a groove in the neck of said bottle to hold the plies together and to receive a cap.

2. The process of forming a bottle of paper consisting in rolling the paper to form the cylindrical body, inserting the bottom with a downwardly projecting flange, folding the bottom walls of the bottle onto the same, and creasing the same, as specified.

3. A paper bottle made up of a plurality of plies, the breast of the bottle formed by, creasing the separate plies and overlapping the same, and a retaining groove for the cap formed in the neck of the bottle, as specified.

4. A bottle formed of one or more plies of paper and a bottom for said bottle with a flange extended downwardly and the sides of said bottle being folded and creased onto the said flange.

5. A bottle made up of one or more plies of paper, with a neck formed by plaitingthe paper and overlapping the same in layers, with a groove for the cap formed therein.

6. A bottle comprising body, neck, and breast portions formed with a plurality of plies of paper, the neck and breast portions having a plurality of plaits in each of the plies thereof rolled in overlapping relation. 7. A bottle made up of plies of paper plaited and overlapping with the bers of 7 my hand and seal in the presence of two 85 witnesses.v
